MOSES W. LEE, OF PHILADELPHIA, PENNSYLVANIA, A SSIGNOR, BY DIRECT ANDMESNE ASSIGNMENTS, TO NATIONAL ROLL PRINTER COMPANY, OF READING,PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

To all whom it may concern:

Be it known that I, MOSES zen of the United States, residing in the cityand county of Philadelphia, State of Pennsylvania, have invented a newand useful Printing Attachment for Rolls, of which the following is aspecification. I

The object of my present invention is to devise a simplified and compactprinting attachment for paper or other sheets which will be accurate andreliable in its action and which may be economically manufactured, andwherein the parts are r'eadilyaccessible for the purpose of inspectionor other purposes. I

With the above in view, my invention consists of a novel construction ofa printing attachment which is adapted to cooperate with a roll of paperor other desired material whereby any desired data may be printed on theroll, as the paper is being with-- drawn therefrom.

It further consists of a novel construction of a support and a. novelmanner of mounting thereon the impression rolland the ink roll.

It further consists of a novel construction of a printing attachment.

It further consists of a novel construction of a support, novel meansfor retaining the ink roll in proper relation with respect to theimpression roll and novel means for placing a tension on the impressionroll so that the same will be maintained in proper engagement' with thepaper which is being withdrawn from the roll.

It further consists of a novel manner 0 mounting the paper roll.

It further consists of other novel features of construction all as will.be hereinafter fully set forth.

For the purpose of illustratingmy invention, I have shown in theaccompanying drawings one form thereof which is at presentpreferred'byme, since the same has been found in practice to givesatisfactory and reliable results, although it is to be understood that'the various instrumentalities of which my invention consists can bevariously arranged and organized and that my invention is not limited tothe precise arrangement and organization of these instrumentalities asherein shown and described.

a casing in which the printing mechanism is adapted to be contained,saidcasing being provided at its top with brackets 2, andremovablecovers 3 and 4. The brackets 2 carry standards 5 in which is journaledin standards being connected at their upper ends by means of a cross bar7 .I

beneath the roll 13, then around the roll and beneath the cutting blade8. 5

The printing attachment is located wlthin the casing land comprises,- inthe present instance, side plates 14 which are connected by means ofcross bars 15 and each of said plates are provided with a slot 16, whichextends downwardly and then forwardly and then upwardly, as indicated at17, thereby adapting the same to receive the journal 18 of theimpression roll 19, which latter at of any desired material, such as forex ample, rubber, which will friction'a-lly engage with understood byreference 'to Fig. 2. The impression roll 19 is providedintermediate theannular strips 20, with an impression plate 21 having the desired datathereon which it is desired to impress or print upon the paper, as it isbeing withdrawn from the roll.

ward end with a downwardly and rearwardly extending slot 22therebyadapting Patented May 27, 1913.

Referring to the drawings:1 designates ing from the front face of theroll passes" its sides is provided with an annular strip Each support 14is provided near its forattachment for paper or other any desired mannera paper roll 6,'said Each bracket 2 is provided with a dependthe paperon the roll 13, as will be the same to receive the journals 23 of theink roll 24, which latter may be constructed in any desired manner, itbeing understood that the ink roll 24 is provided with annular flanges25, which coact with the annular strips 20 on the impression roll 19, sothat the ink pad 24: will cooperate in the proper manner with theimpression plate 21.

26 designates springs one end of which is mounted on one of the journals18, while the other end thereof is mounted on one of the journals 23, sothat the impression roll and ink rolls are always maintained in properrelation with respect to each other.

It will be seen that the slot 12 in the depending brackets 11 is in theunder face thereof, so that in order to maintain the impression roll 20in proper relation with respect to the paper passing beneath the roll13, I provide a tension device'which consists of the bent or curved arms27 which are pivotally supported to the side plates 14 by means offastening devices 28, it being seen.

that the arms 27 near their rear end engage the journals 18 of theimpression roll 19. The forward end of the arms 27 are connected by abar 29 to which latter is secured one end of a spring 30, the other endthereof being seated in a recess 31 in the cross bar 15 of the support.It will be seen that by such a construction, I not only cause theimpression roll 19 to be pressed against the paper passing beneath theroll 13, but I also retain the roll 13 in its proper position.

In the operation, it will be understood that as the paper is wlthdrawnfrom the roll 6 that the ortion passing beneath the roll 13 will, at t eproper time, receive an impression from the data on the printing plate21, so that at predetermined distances apart on the paper, an impressionwill be made thereon of the advertising or other data which is on theprinting plate 21. The paper 18 detached from the roll by the cuttingblade or straight edge 8 in the usual and well known manner.

Special attention is directed to the manner in which the impression rollor the ink roll may be readily removed, it being seen that when it-isdesired to remove the impression roll to place other printingmatterthereon, or for any other purpose, it is simply necessary to pressdownwardly on the impression roll so that the journals 18 thereon willpass rearwardly down the inclined slot 17 and then upwardly in the slot16, so that the parts may be readily removed as s apparent. If it isdesired to remove the ink roll it is simply necessary .to move the sameforward and upwardly whereupon the same will be disengaged upon the slot22 in which the latter is journaled.

' It will now be apparent that have .de-

vised a novel and useful construction of a printing attachment for rollswhich emvmodification in various particulars without departing from thespirit or scope of the invention or sacrificing any of its advantages.
